Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

The Problem with separatingĀ Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. The … Read more

Sequential Cu Pb Zn Flotation Separation

To understand froth flotation, first read that article and come back to read about sequential flotation of Copper, Lead and Zinc. Given a baseline amount of frother and collector, these curves are the approximate/relative rate of flotation recovery of Copper (Chalcopyrite/Bornite/Chalcocite/Covellite/Tennantite/Enargite/Tetrahedrite /Freibergite ), Lead (Galena) and Zinc (Sphalerite) as well as iron (pyrite/arsenopyrite) minerals VS … Read more
